Is it a tablet? Is it a phone? Both, really. You can currently grab the 7in Asus FonePad, which has “all the functions of a smartphone, including calls and texts”, for £179 SIM free at Carphone Warehouse.
Asus FonePad specs include a 1.2GHz Intel Atom processor, 1GB of RAM, and front and rear cameras (1.2MP/3MP).
